Microwave Imaging of Rotating Objects with Narrowband Signals
The experimental investigations as described in this paper are based upon the evaluation of image-field distributions from the scattered fields of rotating objects measured at 36 GHz. Starting with a discussion of the reconstructing formalism and a suitable conversion into Fourier integral form, which is not restricted on small angular ranges, some illustrative examples of reconstruction for simple shaped objects (circular cylinders and flat plates) as well as for a more complex object in the plane of rotation are shown. The effects on the image quality due to various angular ranges used for the computer-aided reconstruction, and problems arising from fictive scattering centers, as a consequence of multiple scattering between various object parts, are discussed.
